(1) Establishing a development application organization;
(2) Learning and training of system development knowledge;
(3) Application for project approval;
(4) preliminary investigation;
(5) preliminary analysis of the current system;
(6) Planning of the new system;
(7) Feasibility analysis of the new system;
(8) Review of the new system.
System analysis
The task at this stage is to build an optimized logical model based on the planning of the new system, including:
(1) Detailed investigation of the current system. First, conduct a preliminary investigation of the current system, basically understand the current system's general situation and existing problems, clarify the main problems to be solved by the new system, and then conduct in-depth and meticulous investigations within the system, and firstly describe the current system comprehensively. Refine and specificize the new system plan;
(2) Analysis of the current system. Analyze the rationality, applicability and effectiveness of the detailed investigation;
(3) Determine the current system improvement comments and the refinement of the new system plan. Determine the logical model of the new system to further clarify the goals and objectives of the new system. Figure 1 shows the problem that the analysis of the system needs to be investigated and analyzed. Figure 2 shows the problem that the system analysis needs to solve.
system design
This stage is based on the logical model proposed in the system analysis stage, establishes the physical model of the system, determines the overall software structure of the system, further decomposes each subsystem into functional modules, establishes the relationship between each module and the internal processing mode of the functional module. Provide information for writing programs, including:
(1) Functional module design of each subsystem;
(2) definition of interface between systems, design of input and output;
(3) Database and information classification coding design;
(4) System operation design;
(5) System design specifications, etc.
Even if the company does not develop software by itself, it must design the system, because this is the basis for choosing to purchase the software. If the system design is not carried out, it is impossible to fully understand what kind of materials are needed, and it is suitable for each sub-system (enterprise department). It can meet the needs of the whole plant and other departments.
System Implementation
The task at this stage is to convert the physical model of the new system into a source program and test it. The specific work is as follows:
(1) Computer system purchase order, installation and acceptance;
(2) programming preparation, including the formulation of programming conventions, selection of programming language;
(3) design of the internal processing of the module;
(4) Programming (if purchasing commercial software, item 2.3.4. should be customized for commodity software);
(5) Software installation test;
(6) database system establishment;
(7) System commissioning;
(8) Prepare various manuals;
(9) System acceptance and identification.
Operation and maintenance
This stage is to ensure the normal, reliable and safe operation of the system, play the role of the system, continuously improve and improve the system, improve the operation quality of the system, reduce costs, and promote the improvement of enterprise technology and management level. The main work includes:
(1) Improve the organization and rules and regulations of system operation;
(2) Make a good running record;
(3) maintenance of the database system;
(4) Maintenance of information classification code;
(5) Maintenance of application software.
